Average CPU temperature by cores data

[alozovskoy]

https://github.com/afaqurk/linux-dash/issues/451 - Getting an average value of CPU cores temperature when sensors not return "Physical" metric.

Unfortunately, i can't check it on real hardware (all my devices return data with "Physical" metric), but it work on "synthetic" tests.

I was looking to apply this pull request but it needs lm-sensors to be installed otherwise it won't work.

Had to make a change in my dashboard to work (ubuntu 18),

first change, $(type -P sensors 2) .old code was including the /usr/bin/sensor in the json second -f 7 instead of 3 to get the temp value

hope you find it useful

cpu_temp() { local ID= [ -f /etc/os-release ] && source /etc/os-release case "$ID" in "raspbian") cpu=$(</sys/class/thermal/thermal_zone0/temp) echo "$((cpu/1000))" | _parseAndPrint ;; ) if "$(type -P sensors 2)" >/dev/null ; then returnString=sensors

amd

    if [[ "${returnString/"k10"}" != "${returnString}" ]] ; then
      $ECHO ${returnString##*k10} | $CUT -d ' ' -f 6 | $CUT -c 2- | $CUT -c 1-4
    #intel
    elif [[ "${returnString/"core"}" != "${returnString}" ]] ; then
      fromcore=${returnString##*"coretemp"}
      $ECHO ${fromcore##*Physical}  | $CUT -d ' ' **-f 7** | $CUT -c 2-5 | _parseAndPrint
    fi
  else
    $ECHO "[]" | _parseAndPrint
  fi
;;

esac }

@Surrealcrow or simply add |"ubuntu" after "raspbian" in the switch/case block.

It has the first advantage to not need to have lm-sensors to be installed 😉

@Jiab77 i was thinking about that, however after a test i noticed that the reported temp in the raspian option was off by some degrees, I don't really know if it is only my case.

thanks!

Hi, I have same problem on my intel based PC under linux mint 20.04

sensors output was:

                       (crit = +79.8°C)

so I fixed it like this on my code local copy:
